How to Sync Google Calendar With Outlook: The 2026 Step-by-Step Guide

If your meetings live in Google Calendar but your company runs on Outlook, you already know the friction I’m talking about. An invite lands in Google and just never shows up next to your Outlook meetings. You block time in one place, then get double-booked from the other. The two calendars never quite agree on what your day looks like.

I’m Nir Sabato, co-founder of Catch, the AI executive assistant built to take admin work off executives’ plates. A lot of my days are spent with leaders at US mid-market companies, and “my Google and Outlook calendars don’t agree” is one of those small, recurring headaches that quietly eats into the day. The fix is quick. Connecting the two takes a few minutes, and once it’s done you finally get one clear view of your schedule.

This guide walks through every reliable way to sync Google Calendar with Outlook in 2026: adding your Google account directly to the new Outlook, subscribing to Google Calendar in classic Outlook, getting the Outlook-to-Google direction working, and what to do when you actually need true two-way sync. And at the end, I’ll show you what a synced calendar really unlocks.

First, Know Which Direction You Need

Before we touch any settings, one quick bit of clarity, because this is where most people trip up. “Syncing” can mean two different things, and they don’t work the same way:

• Google Calendar → Outlook. You want your Google events to show up in Outlook. This is the common one if your personal or work calendar lives in Google but your company runs on Outlook. There are two solid ways to pull it off, depending on which version of Outlook you’re using.
• Outlook → Google Calendar. You want your Outlook events to show up in Google Calendar. That’s the reverse, and it takes a slightly different path.

Plenty of people actually want both: a single calendar that reflects everything, no matter where an event was created. I’ll cover each direction, then get into real two-way sync and the simplest setup of all.

Worth saying up front, though. Google and Microsoft don’t give you a single built-in button that keeps both calendars perfectly mirrored in real time. The native methods below each have one specific job, and between them they cover the vast majority of needs. For genuine live two-way sync, there’s a dedicated option I’ll get to later.

How to Sync Google Calendar With Outlook (New Outlook and Outlook on the Web)

If you’re on the new Outlook for Windows or Outlook on the web, the cleanest method by far is to add your Google account directly. That pulls in your Gmail and your Google Calendar together, and lets you see and manage your Google events right next to your Outlook ones.

1. Open the new Outlook app (or go to Outlook on the web and sign in).
2. Click the Settings gear in the top-right corner.
3. Go to Accounts, then Email accounts.
4. Click Add account and enter your Google email address.
5. You’ll be redirected to Google’s sign-in screen. Sign in with your Google credentials. If your company uses two-factor authentication or single sign-on, follow the prompts to approve it.
6. Review the permissions Google asks for and approve them so Outlook can access your calendar.
7. Once the account is connected, open your Calendar in Outlook. Your Google calendar will appear in the left-hand list - tick the box next to it to show it.

Your Google events now show up inside Outlook, and the connection keeps them current on its own. This is the most modern, lowest-maintenance way to get Google Calendar into Outlook, and it’s where I’d start if your version supports it.

Note: Some company-managed Outlook setups block adding outside accounts. If you don’t see the option, or it’s greyed out, that’s an IT policy thing. Check with your admin, or just use the subscription method below instead.

How to Add Google Calendar to Classic Outlook (ICS Subscription)

If you’re on classic Outlook for Windows (or you simply can’t add a Google account directly), the reliable route is to subscribe to your Google Calendar using its secret iCal link. That puts your Google events in Outlook and keeps the feed refreshing.

Step 1 - Get the link from Google Calendar:

1. On a computer, open Google Calendar.
2. Hover over the calendar you want in the left sidebar, click the three dots, and choose Settings and sharing.
3. Scroll down to Integrate calendar.
4. Find the Secret address in iCal format and copy the full URL. (Keep this private - anyone with the link can see your events.)

Step 2 - Add it to Outlook:

1. Open Outlook and go to your Calendar.
2. On the Home tab, click Add Calendar, then choose From Internet.
3. Paste the iCal URL you copied from Google.
4. Click OK. When Outlook asks if you’d like to subscribe and receive updates, click Yes.

Your Google events will show up in Outlook as a separate calendar and refresh on their own. Two things to keep in mind here. First, it’s one-way (Google → Outlook), so you can view your Google events in Outlook, but you still create and edit them over in Google. Second, subscribed internet calendars refresh on Outlook’s own schedule rather than the instant something changes, so a brand-new event may take a little while to surface.

How to Sync Outlook Calendar With Google Calendar (the Other Direction)

Now for the reverse: getting your Outlook events to show up in Google Calendar. You’ve got two practical options here.

Option 1: Publish your Outlook calendar and subscribe in Google

This is about as close as you’ll get to an ongoing sync in this direction. It works best with Outlook.com and Microsoft 365 calendars that support publishing.

1. In Outlook on the web, go to Settings > Calendar > Shared calendars.
2. Under Publish a calendar, pick the calendar you want and choose a permission level (the option that shows full details).
3. Click Publish, then copy the ICS link Outlook generates.
4. Open Google Calendar on a computer. In the left sidebar, find Other calendars, click the +, and choose From URL.
5. Paste the ICS link and click Add calendar.

Your Outlook events now show up in Google Calendar. Like any subscribed feed, it’s read-only on the Google side, and Google refreshes URL calendars on its own schedule, so new events can take a while to land.

Option 2: Export and import a one-time copy

If you just need to move events over once (say, you’re switching systems), you can export from Outlook and import into Google:

1. In Outlook, open the calendar, go to File > Save Calendar, and save it as an .ics file (or export from Outlook on the web).
2. In Google Calendar, click the gear icon > Settings, then Import & export in the left menu.
3. Choose your .ics file, pick which Google calendar to import into, and click Import.

This brings your existing Outlook events into Google as a snapshot, and that’s it. It does not keep updating, so events you add in Outlook afterward won’t flow over. Use this one only for a clean one-time transfer.

When You Need True Two-Way Sync

Each of the native methods above handles one job well. What none of them do is keep both calendars mirrored in real time, where an event created or edited in either place instantly updates the other.

If that’s what you’re after, and for a lot of executives juggling a personal Google calendar and a work Outlook calendar it is, you’ve got a couple of options:

• Google Workspace Sync for Microsoft Outlook (GWSMO). If your organization runs on paid Google Workspace and you use the Outlook desktop client, Google’s own GWSMO tool keeps Gmail, Contacts, and Calendar in sync. It’s built specifically for Workspace customers.
• A dedicated third-party sync service. A handful of reputable tools keep a Google and an Outlook calendar mirrored in both directions, updating each when the other changes. If you genuinely need live two-way sync across two separate accounts, this is the category to look at.

For most people, though, the cleanest answer isn’t more syncing at all. It’s picking one calendar as your source of truth.

The Simplest Setup: One Source of Truth

Here’s the advice I hand executives most often. The goal isn’t to mirror everything in every direction, since that’s exactly how you end up with duplicate events and that nagging question of which entry is the real one. The goal is one calendar you trust and one place you look.

For most leaders at mid-market companies, that’s wherever the invites actually land and where your team books you. Sync the other calendar into it for visibility (using the steps above), then make a habit of creating every new event in your source-of-truth calendar. You get one reliable schedule across your devices, and you stop wondering which version is correct.

Once that’s in place, the question stops being “are my calendars synced?” and turns into “who’s actually running this calendar?”

Where Syncing Stops and Real Help Begins

Syncing solves the visibility problem: your meetings show up where you need them. What it doesn’t touch is the actual work of running a calendar. A synced calendar still won’t resolve a conflict on its own. It won’t reschedule the meeting that just collided with your flight. And it definitely won’t coordinate a time across four people, send the invite, and then chase down the one person who never replies.

That’s the part that still eats an executive’s day, and it’s exactly what we built Catch to take over.

Catch is an AI executive assistant that connects to your calendar (the same standard connect-your-calendar setup you’d use for any integration, and it works with both Google and Outlook) and then actually runs your schedule for you. A few examples of what that looks like in practice:

• It resolves conflicts end-to-end. Catch watches your calendar continuously. When two meetings collide, it doesn’t just flag the problem and leave it with you. It reaches out to reschedule and gets it sorted.
• It schedules new meetings across channels. Ask Catch by text, iMessage, Slack, email, or voice (“set up 30 minutes with the sales team next week, mornings only”) and it checks your calendar, coordinates with everyone, and sends the invite.
• It books the links other people send you. Someone emails you a scheduling link? Catch reviews the open slots and books a time that actually works for you, rather than letting it sit in your inbox for three days.
• It generates scheduling links in seconds, with whatever constraints you set.

So once your calendars are synced and visible, Catch is what turns that calendar from something you manage into something that manages itself. It works wherever you already are (Slack, email, text, iMessage, and phone) for a flat $99/month, with no per-call fees.

Syncing your calendars is step one. Handing the busywork off entirely is the step that actually hands you back your time.
